DRYING-ROOM T'UMBLER.

Application filed June 23, 1927. Serial No. 200,981.

This invention relates to drying room tumblers of the type described in my pending application Sr. No. 183,195, filed April 12, 192 and has for its object a construction by which the drying is facilitated by a slow current or change of air created by the piston or pumping action of the oscillating clothes support with the clothes thereon. v

The invention consists in the novel features m and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which J like character designate corresponding'parts inall the views.

Figure 1 is a lengthwise vertical sectional view of this tumbler or drier.

Figure 2 is a vertical cross-sectional view.]

- Figure 3 is an enlar ed fragmentary sec- .10 tional view of the clot es support and the contiguous part of the cylindrical body.

Fig. 4 is a detail of the inlet damper. Y This dr ing room tumbler comprises a cylindrical ody arranged with its axis horizontal, an oscillating support mounted in the body to oscillate above and below the horizontal plane of the axis of the body, the sup- 7 port being mounted coaxially with the body and means 'bywhich a heated current of air is drawn by the suction action of the support when oscillating in one direction into the-body and is held from movement out of the body during the oscillation of'the support in the other direction whereby itis compressed and forced through the clothes on the support 1 designates the body which iscy indrical in general form and mounted upon a suitable hollow base 2 which" encloses the air chamber 3 to be presently described. p

4 is the oscillating support mounted on a shaft 5 arranged coaxially in the body 1 and connected at one end to a suitable actuating mechanism designated generally by the neference numeral 6. The body 1 has a suitable cover 7 at its top -for permitting the clothes to be inserted and removed. The support 4. is mounted to oscillate in opposite directions above and below the horizontal plane of the axis of the shaft 5o 5' and is provided with openings through which the air can pass during the oscillating action. hese openings are provided by forming theintermediate portion of the sup} port 4 of mm mesh 8. This support is a sheet metal frame and has a hub 9 on the shaft 5. "The support slidably fits the perlpheral and end walls of the bodyl so that the support acts as a piston to draw in and compress the air during the oscillations thereof and it is formed at its margins with spring pressed packings 10 which arepfessed outwardly by springs 11 against the walls of the body 1. The packing and springs are located between the upper and lower sheet frame metal pieces 12 of the support.

The support is also formed with deflectors 13 extending lengthwise of its upper side parallel to the axis of the shaft 5- and located near said axis, these deflectors preferably having downwardly inclined sides so as to cause the clothes to turn over when tumbling from'one' side of the shaft to the other.

The walls of the hollow base 2 have tapering extensions l t-extending into the body 1 forming a hollowpartition in the lower half of the body 1 and heating coils 15 are located in the air chamber. The air chamber has a suitable inlet 16 for air which can be partly or wholly closed by a closure 17. One of the walls 14 is formed with holes 18 thercthrough and the other wall is formed with a comparatlvely large opening 19 closed by a check valve 20 which opens into the interior of the body 1. A breather opening 21 is located in the upper portion of'the body.

In operation, the clothes are placed on the support and during the oscillation thereof,

will be thrown from one side to the other of r the shaft 5, the baffle 13 causing them to turn over during the tumbling operation. During the oscillating movement to the left, Figure 2, the clothes will be thrown from the right hand side of the sup-port to the left hand side and durin the-first part of such movement,

the right and side of the support will act during itsupward movement as a pistonto draw air through the holes 18 and when the support reaches the dotted line position, Figure 2, the clothes will be thrown and turned over onto the left hand side of the support which is in its down or dotted line position, Figure 2. Now, during the reverse operasupport with wardly, this lefthand side with the clothes thereon forms apiston to draw air in past the flap valve 20 until the clothes tumble from the left hand side to the right hand-side of the support. During the next reverse operation, the support with the clothes thereon tion, at whichtime the left hand side of the the clothes thereon moves upwhich havetumbled from the right hand side out throu h the breather opening.

to the left hand side of the support compresses the portion of this air against the flap valve causm the air to pass through the clothes on thefieft hand side of the support and dur- 1n the upward movement of the left hand si e of the support some of the air that has passed through the clothes will be forced the breather opening. Thus, during eac oscillation of the support, some new dr air is drawn into the body and passed through the clothes and some ofthe moisture laden air-above the clothes passes out through Thus, a slow but efiective circulation or change of air is effected. The air pressed by the right hand side of the support with the clothes thereon back into the air chainber 3 is dried and passes out past the flap valve. The closure 17 is opened far enough to supply enough airto the air chamher to compensate for that displaced out of the air chamber by the suction action of the at I claim is: I
